Here are some terms we use:
Budget Grade = Bare rooted, a baby plant or pup, ships wrapped in potting mix, will need some TLC before planting out into a large garden. Landscape Grade = >1 Litre or more, strong and healthy for planting out. Premium Grade = >1.3 Litre or more, larger than landscape Grade, nice and bushy. Superduper Grade = >3 Litre or more, may have multiple stems, very bushy, an eyecatcher :-)
Please note : All our plants have their own unique characters and the photo is a guide to show what the plant looks like. There may be variations of shape and sizes... but they will look happy and healthy when you receive them!
Own-root roses are roses grown from cuttings taken from stock plants. Unlike grafted roses, the roots of own-root roses are the same variety as their flowering tops.
Plant Zero Nursery does not do any budding or grafting of roses. Unlike the majority of rose growers, we sell only own-root, virus-free roses. Our roses are first-year cuttings that are grown from a leaf cutting taken from a “mother” or “stock” plant. Own-root roses may be smaller when purchased, but quickly catch up to grafted roses (which are usually sold as two-year-old plants).
Growers initially began producing own root-roses as a response to the prevalence of Rose Mosaic Virus within the industry. This nasty virus was spread through grafting. Growers found that they could greatly reduce the spread of RMV if they used virus-free stock plants. Soon the industry discovered that roses grown on their own natural roots (and not those of another variety) had other advantages too:
Most varieties grow rapidly their first year, though they seem smaller than their grafted counterparts. There is a saying with own-root roses:
The first year they sleep; the second year they creep; the third year they leap!
When an own-root rose is 3 years old, it will be identical in size to a grafted rose of the same age (if not sooner).
Q: Can a rootstock improve the disease resistance of a rose grafted onto it?
A: No, but it can improve the vigor.
Budding was the primary method of producing roses in the late 1800s. ‘La France,’ the first hybrid tea rose, had a beautiful bloom, but the plant was weak. By budding it onto rootstock, it took on more vigor and budding soon became the method of producing the modern rose.
Own-root roses are not the best choice for instant gratification. However, vigor, hardiness, and the elimination of budding and grafting guarantees that the rose you selected, loved, and cared for will always be that same rose. If you live in a cold climate or have a rose that started off one color and is now another color (because the top died and the rootstock took over), give own-root roses a try. They are a superior product.
